Today, 53 percent of corporate entry-level jobs are held by women ... Men are twice as likely as women to advance at each career transition stage. One rationale is that men are more likely than women to do things that help their personal well being at work, thus negating burnout, according to the Captivate Network. Men are 25 percent more likely to take breaks throughout the day for personal activities, 7 percent more likely to take a walk, 5 percent more likely to go out to lunch, and 35 percent more likely to take breaks “just to relax.”

According to MTV's new "No Collar Workers" study, Millennials have a real desire to connect with their work and would “rather have no job than a job they hate." With this need for a sense of purpose and technology playing a major role, it's easy for young people to work around the clock without even realizing it.

The lines are blurred between work and play because young people want to enter careers that they enjoy, Dhawan told us. Hence, if they enjoy their careers, they'll most likely put more time into it. In fact, college-educated Gen Y-ers can have a nine-to-five job and also have their five-to-nine job where they're freelancing or working on launching an organization.

"More elite Millennials are more likely to change jobs or have one or two jobs at the same time," Dhawan says. "They have less loyalty to any one type of job, but have more loyalty to their sense of purpose."
